A non-contact power supply apparatus is configured to transmit power in a non-contact manner from a primary-side coil to a secondary-side coil by supplying alternating current power to the primary-side coil. The non-contact power supply apparatus is provided with an alternating current power output unit, a power transmitting unit, wiring, a detecting unit, and a determining unit. The alternating current power output unit is capable of outputting alternating current power. The power transmitting unit has the primary-side coil. The wiring electrically connects the alternating current power output unit and the power transmitting unit to each other. The detecting unit detects a ratio between an output voltage and an output current, which are outputted from the alternating current power output unit, or a phase difference between the output voltage and the output current. On the basis of the ratio and/or the phase difference detected by means of the detecting unit, the determining unit determines whether an abnormality has generated or not in the non-contact power supply apparatus.
